To al w/Lom it may concern:

Be it knovrn that I, T1msn N. Marnnws.

a citizen of the United States ofAmerica, and resident of'i-Vellsburg, county of Brooke, and State of lVest Virginia, have invented certain new and useful Improvements in Regenerative Glass-Furnaces, of which the fol` lowing is a specification.

This 'invent-ion relates broadly to glass furnaces, and more specifically to a regenerative furnace.

The primary object of the invention is to i provide a regenerator glass furnace which embodies in its refining and cooling end' `gases in a relining and cooling chamber of the open character heretofore commonlyemployed, the glass is not only discolored by Contact with the products of combustion and contaminated by particles of carbon and other impurities carried by the gases or resulting from combustion, but it is more or less violently agitated by the burning vheat absorbed thereby, which causes foreign particles to be carried to the surface in they forni of cords or seeds, resulting ultimate-ly in excessive Wastage and an inferior product.

-As hereinbefore indicated, it is a purpose of this invention to obviate the objections just recited by the provision of mutile arches in the refining and cooling chambers.

A further object is to provide, in a furvnace of the character mentioned means p'anying drawings, in Which- Figure 1 is a generally horizontal section v of the refining, cooling and regeneration chambers of a. regenerative furnace;

Fig. 2 is an enlarged longitudinal section taken substantially on line 2-2, F ig. l;

Fig. 3 is a transverse section taken approximately lon line 3 3, Fig. 2;

Fig. t is a dia-grain illustrative of the companion damper arrangement employed in the regenerator flues; and- Fig. 5 isa section on line 5 5, Fig. 1.`

Referring to said drawings, in which like designating characters distinguish like parts throughout the several views- 1 indicates tivo oppositev sides of a refining chamber, said sides being separated by an air space 2 and merging at their forward ends into a single longitudinally disposed cooling chamber 3 which extends forward to the Working point (not shown). Lo cated over said refining chambers 1 and the cooling chamber 3 and separated therefrom by niufiie arches l composed of refractory blocks or tiles in the combustion chamber 5. iGas is introduced in said combustion chamber at separated points or spacedintervalsthroughout its length through ports 6. to

which the gas is conducted throughpassages 7 leading from a regenerator heating cham-` ber or chambers 20 of common checkered form located laterally with respect to vsaid combustion. chamber. Air for supporting combustion also enters the combustion chamber with the gas so as to be thoroughly com-` mingled or mixed with the latter, such air beingv conducted upward to the various passages 7 through passes 8 leading from regenerator air chambers 9. l

As is obvious, the arrangement oft-he 'r generator heating chambers 20 and 9 with their passages and ports at opposite sides of the combustion chamber pro-vides for their alternate employment as inlet passages for -gas and air and as outlet passages for Waste gases according to the regenerative principle. Control of the direction of trzvel is had through suitable oppositely arranged dam- .pers, as 13, suspended in tiues 21 at opposite ends of a cable 14 which is disposed across the top Iof the furnace and which operates upon sheaves or pulleys 15, one of said dam- ,pers being in elevated 'flue-.opening position When the other occupies 'its lQWered-ue-closing position. i. i

Located in front of the regenerator heating chamber?) at each side'of the furnace 1s a regenerator chamber 16 associated with the cool-ing end of the combustion chamber 5 of the furnace, the same being designed to introduce'gas and air over themuflle arch in said cooling end in' preciselythe same inan-v ner as over the arches ofl the ,refining chambers hereinbefore referred to.

Located laterally with respect to the'regenerator chambers 9. and 16'at opposite lsides of the furnace and communicating with said chambers through ports or flues 10' located at intervals at or .near the, bottoms offthe outerv side Walls of the latter are auxiliary air 'chambers l1 to which air isV conducted' through apipe or`pipes l2 lead-4 ingfrom a suitably located fan or'bloiver (not shown), or air at atmospheric press ure maybe supplied therethrough.

The bottoms or floors of the refining chambers are upwardly and forwardly in.

-' clined, as slioyvn'a-t 1'?, atthe end thereof ad- I jacent to'the throatslS through which the glass flows to said chamber from the'melting chamber 19. This renders 4the forward ends of said refining chambers and the cooling chamber of relatively less depth so that theglass in rsaid' chambers will be heated throughout to a substantially uniform temperature.

vWhatis claimed isl. In a regenerative @dass furnace, 'a'pair of refining chambers disposed side by side and suitably separated, a cooling chamber located forward of said refining chambers landV having the latter communicating therewith at their front ends, a combustion cham-f Vber located over-said. refining and cooling chambers, ,and muffle arches overlying said refining chambers and 4the cooling chamber Vand separating the same from said .coinbustion chamber.'

2. In a regenerative glassfurnace, the

combination With a -melting cham-ber, of separated refining chambers to which glass flows from said melting chamber, said re-v having ,their bottoms fiiiing chambers e located at ahigher level than that of said melting chamber, a lcombustion chamberlocated vover said refining chambers. and.

muffle archesl overlying said refining chambers and separating the same from said com bustion chamber.

3. In a. regenerative glass furnace, the

combination with a melting chamber.v of separated refining chambers to which glass flows from said melting chamber, said re' fining chambers. having their bottoms ReSSeS.

located at a higher level than that of said melting chainbei, a 'cooling chamber located forward of, said refining chambers andv in open communication with thelatter, inutile arches overlying said refining chambers and said cooling chamber, and a `combustion chamber located over said mu'iiie arches. a

l. In a regenerative .glass furnace', the

vcombination with a melting chamber,v ofa plu ality of refining chambers arranged sidtl by side and separated by intermediate air spaces, throats 'through which glass flows from 'said melting -chamber to said refining chambers, a. cooling chamber located foryvard of said refining chambers and in open -communication'yvith the front ends' of the latter, a combustion chamber lo ated over said refining chambersand vsaid cooling chamber, and in uffle arches separatingthe Vlast-mentioned chambers from said coinbus tion chamber.

5. In'l a regenerative vglass furnace, the

,combination with a melting chamber. of a plurality of refining chambers arranged sido by side and separated by intermediate air spaces', throats through Which glass flows from said melting chamber to said refining chambers, the floors'of said refining cham- 'bers being located on a level aboefhat ot'- 'sai.d.tliroats, a cooling chamberlocated forward of said refining chambers and in open communication with the front ends` of the latter, a combustion clia'mber located over said refining. chambers andV said Acooling chamber, andv inufiie ,arches separating thc deste-mentioned chambers from said combusbustion chamber through saidl regenerators.
